As I found out from posting my current 2010 digs, my list is rather short
of stuff. So what do I need to fill it out? Here are some things I was
looking at to start off. PS - Don't bother giving me Metal recs unless it's
drone or something like that.

Yeah I though their absence from this list was strange. 6, 7, 21 and 22 are all top 5 contenders for me atm so I'd recommend starting with those. I'd also add Kvelertak's self titled though I suppose you could classify that as metal.
